it's trad, dad (1962)

aka Ring-a-Ding Rhythm!.
"When the music finishes we'll try and sneak past them."
When the mayor of a new town has his coffee interrupted by teens listening to trad jazz, he decides to ban this hellish music. So its up to Helen (Helen Shapiro) and Craig (Craig Douglas) to try and enlist some DJ's and musicians to put on a concert and convince the mayor he is wrong.
If you wade through the mass of trad jazz on show, there are some gems to be found in this compendium of music, such as Gene Vincent, and Gary U.S. Bonds. In between the artists Dick Lester gets to audition his comedic style waiting for the right vehicle to arrive a couple of years later when the Beatles swept much of this music aside.
